Frontal parosteal lipoma.

Parosteal lipoma of the head and neck is very rare, and there is no reported case of parosteal lipoma in the frontal region. We present the case of frontal parosteal lipoma in a 20-year-old man who was referred for a forehead mass causing a cosmetic problem. Computed tomography revealed an osseous projection with cortical irregularity and soft tissue enlargement. Excision of the lesion revealed a 7 x 4.5-cm lobulated, encapsulated, yellow tan mass. Histopathologic examination revealed mature adipose tissue, and pathologic diagnosis of lipoma was made. Here, we present the first case of parosteal lipoma in the frontal region.
